Description
Technical field
This utility model relates to a kind of radar levelmeter, particularly relates to a kind of radar level gauge system.
Background technology
Radar levelmeter is measuring instruments based on time stroke principle, and radar wave runs with the light velocity, reflects and is received by the receptor in instrument, and by electronic unit, distance signal is converted into thing position signal when running into material surface.Radar level gauge system is widely used in determining the packed height of the product accommodated in tank.Radar levelmeter amount is typically carried out by not contact measurement or contact measurement, wherein, the product transmission of electromagnetic signals that contact measurement does not accommodates in tank, the contact measurement being commonly called guided wave radar (GWR) has then relied on the probe of waveguide effect electromagnetic signal guided and import in product.Probe is generally positioned to extend vertically to tank bottoms from tank deck.Probe also can be disposed in the most so-called chamber of measurement pipe that the outer wall with tank is connected and is connected with the internal flow of tank.Radar wave is radiated in target, can encourage surface current at target surface, and these surface currents, as source of secondary radiation, produce electromagnetic wave and blaze abroad, thus create reflection or scattering.Reflected signal is by the receptor being included in radar level gauge system or transceivers.Based on to sending signal and the analysis of reflected signal and calculating may determine that the position of material, but current radar levelmeter is when measuring, need through longer time tranfer and feedback, in during the measurement that this is longer, the very possible signal occurring that transmission is returned is inaccurate or the situation of virtual echo occurs, or in the case of operating mode is more complicated, so make not can accurately the echo of analyte position, measure inaccuracy.Additionally, material medium character is different, its dielectric constant is the most different, the conductivity of the size reaction medium of dielectric constant, the big conductivity of dielectric constant is big, and attenuation rate is little, this means that radar wave touches dielectric surface after launching and has individual penetrating, the least more deep attenuation penetrated of dielectric constant is the biggest, and then signal has been decayed, and the distance transform penetrated thus becomes the time to change into liquid level through microprocessor to exist for inaccurate situation.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of quickly measurement, the echo of accurate analyte position, the radar level gauge system that certainty of measurement is high.
For solving above-mentioned technical problem, the technical scheme that this utility model is taked is: a kind of radar level gauge system, including the tank body in hollow form and the radar levelmeter being installed on tank body, tank body is provided with the installation conduit for installing radar levelmeter, described radar levelmeter is connected with installing conduit upper end, it is provided with a vertical conduit in the tank body of underface of conduit is installed, vertical conduit is connected with the lower end installing conduit and extends to the bottom of tank body, the tube wall of vertical conduit is provided with multiple linked hole come round with tank body, the metallic reflection plate of a hollow it is provided with in vertical conduit, metallic reflection plate can move up and down in vertical conduit.
As further improvement of the present utility model, described radar levelmeter includes electromagnetic horn, and electromagnetic horn extend in vertical conduit.
As further improvement of the present utility model, described vertical conduit is nonmetallic materials pipe.
The beneficial effects of the utility model are: the installation conduit on tank body is easily installed or safeguards radar levelmeter, vertical conduit is come round with tank body, aqueous material can enter in it, play communicating pipe effect, the metallic reflection plate of hollow floats on aqueous material, and move up and down in vertical conduit along with the variation of thing position, metallic reflection plate is good conductor, it is the biggest that radar wave is radiated at the surface current produced above, therefore reflection is the biggest, echo signal intensity is high, the process of true echo and the identification to the various interference signal echos being mixed with are more prone to by processor, measured value is accurate, the deflection of the density different metal reflecting plate simultaneously taking account of aqueous material is the most different, liquid level is changed into the most accurate through microprocessor；Vertical conduit uses nonmetallic materials pipe, and electromagnetic horn extend in vertical conduit so that it is the least that radar wave is radiated at the surface current produced above, is almost negligible, and further reduces reflection interference signal, it is ensured that measurement accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of radar level gauge system of this utility model.
Wherein, 1: tank body；2: radar levelmeter；3: conduit is installed；4: electromagnetic horn；5: vertical conduit；6: metallic reflection plate；7: linked hole.
Detailed description of the invention
With specific embodiment, this utility model is further elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model one radar level gauge system, including the tank body 1 in hollow form and the radar levelmeter 2 being installed on tank body 1, tank body 1 is provided with the installation conduit 3 for installing radar levelmeter 2, described radar levelmeter 2 is connected with the upper end installing conduit 3, it is provided with a vertical conduit 5 in the tank body 1 of underface of conduit 3 is installed, vertical conduit 5 is connected with the lower end installing conduit 3 and extends to the bottom of tank body 1, the tube wall of vertical conduit 5 is provided with multiple linked hole 7 come round with tank body, the metallic reflection plate 6 of a hollow it is provided with in vertical conduit 5, metallic reflection plate 6 can move up and down in vertical conduit 6.Installation conduit 3 on tank body 1 is easily installed or safeguards radar levelmeter 2, vertical conduit 5 is come round with tank body 1, aqueous material can enter in it, play communicating pipe effect, the metallic reflection plate 6 of hollow floats on aqueous material, and move up and down in vertical conduit along with the variation of thing position, metallic reflection plate 6 is good conductor, it is the biggest that radar wave is radiated at the surface current produced above, therefore reflection is the biggest, echo signal intensity is high, the process of true echo and the identification to the various interference signal echos being mixed with are more prone to by processor, measured value is accurate, the deflection of the density different metal reflecting plate 6 simultaneously taking account of aqueous material is the most different, liquid level is changed into the most accurate through microprocessor；
Another kind of improve embodiment as of the present utility model, described radar levelmeter 2 includes electromagnetic horn 4, and electromagnetic horn 4 extend into about 30-100mm in vertical conduit 5, it is to avoid installation conduit 3 produces interference signal.
As another kind of improvement embodiment of the present utility model, described vertical conduit 5 is nonmetallic materials pipe so that it is the least that radar wave is radiated at the surface current produced above, is almost negligible, further reduce reflection interference signal, it is ensured that measurement accurate.
